Fiberglass, or any composite will require that you 'build' every component at least 'three' times ( a big reason to get the design correct the first time ).
1) usually a plaster 'plug' is created, which represents the final appliance in every detail.
2) from the 'plug', a plastic-faced, plaster 'tool' is created, which will be the 'mold' from which the final 'part' is cast.
3) the 'part' begins with a fully-prepped mold ( 3-layers of carnauba wax, and a spray coat of polyvinyl alcohol release film ), then gel-coat, followed by successive layers of either pre-preg fabrics, matt, or tapes, of cross-oriented layers, or wet layups, preferably vacuum-bagged and autoclaved simultaneously.
4) Some epoxy systems can be post-cured outside in the heat of the Sun.
5) There are really good books on the subject.
6) I suppose there are good instructional videos available online.
7) I spent a few $ thousand on an advanced composite course near Reno, Nevada @ Abaris which has paid dividends ever since.
